Hansen urges students to find the ideal place to study, with as few distractions as possible.

Hansen described one of his best students, who in the first week of school, committed to meet at least one new person in each of his classes. This strategy expanded his network of friends and was a resource if he missed a class.

Hansen urges students to stay on campus as much as possible because the more time spent getting to know the campus and new friends, the more at home they will feel.

Manos added that if a student really feels the need to go home, they shouldn't resist the urge because they may need the support from home.

More than 3 million students will enter higher education this fall. More than 20 percent will drop out during the year, according to several national studies.

For some, it's a lack of money. For others, it's a lack of studying, homesickness or a loss of direction.
